Redbar Anthias description

The Redbar Anthias male bears a light pink body and owing to its name, has a vertical red bar that runs along the mid-section of the body. The females on the other hand have a rather orange body with a silvery belly and a red tail.

As with other Anthias species, the Red-Bar Anthias are hermaphrodite with the largest and dominant female of the group often morphing into a male in the absence of other males.

Redbar Anthias in the ideal aquarium

Redbar Anthias - Pseudanthias Cooperi

Setting up the best aquarium home for the Red-Bar Anthias would require a well filtered aquarium of 70 gallons/265 litres tank to house single Princess Anthias.
However, if they should be housed in a group of one male with few females, a minimum of 125 gallons/473 litres tank or larger will be just perfect.

Although they are middle dwellers, they enjoy a tank with lots of caves and live rocks that will provide them with plenty of hiding places.

Redbar Anthias feeding

Redbar Anthias are carnivores with high planktivorous appetite.

They can be fed with meaty foods including live and frozen mysis shrimp, enriched frozen brine shrimp. An attached refugium that ensures the cultivation of copepods and amphipods will also provide these species with nutritious live foods.

With time they will accept high-quality flaked foods, but should be offered in small quantities throughout the day.
